Double-lumen flow-through swivel for chronic experiments with unrestrained monkeys.
Two modifications of a flow-through swivel are described for prolonged infusions into and simultaneous blood-sampling from chronically implanted catheters of large, unrestrained animals, e.g., rhesus monkeys. In addition, both offer easy access to the catheters proximal to the swivel and to the lumen of the reinforced nylon tubing which connects the animal to the swivel.
